Definitions

  • This invention relates to an apparatus for deploying an emergency breathing mask in an aircraft.
  • the apparatus is automatically or manually operable to present the breathing mask to a user upon loss of cabin pressurization.
  • the masks 16 may have to be replaced after a predetermined period of time, the masks may have to be repacked after inspection or they may have to be repacked after a deployment.
  • components which typically include the oxygen tubes 29, reservoir bag 38, elastic strap 34 and lanyards 60, must be carefully folded and coiled as shown in Fig. 1B so that the mask 16 deploys properly and does not become tangled during an emergency situation.
  • the process of repacking masks is time-consuming and costly given the labor rates of aircraft technicians.
  • the present invention meets the above-described need by providing a method and apparatus for presenting oxygen masks that provides a pre-packaged, modular system that does not require manual repacking of oxygen masks by aircraft technicians.
  • the system also provides a force other than gravity for deploying the masks. It is to be understood that the present invention may be used in a ceiling mounted orientation where it would provide a force in addition to gravity for releasing the masks.
  • a cartridge 100 which may be in the shape of a cylinder, contains a single oxygen mask assembly 103.
  • the oxygen mask assembly 103 may include the following major components: a folded reservoir bag 106, an oronasal mask 109, a strap 112, and breathing conduit 115.
  • the cartridge 100 is provided with side walls 118 and an end wall 121.
  • the end wall 121 is provided with an opening 124 for receiving a quick connect fitting that is in fluid communication with the conduit on the mask assembly.
  • the cartridge 100 Opposite from the end wall 121, the cartridge 100 has an opening 127 where the mask 109 exits the cartridge 100 during deployment.
  • the opening 127 may be initially covered or partially covered by a removable substrate 130 which may be provided with a pressure-sensitive adhesive or the like. Alternately, the substrate 130 may be creased, scored, or perforated such that it will split open during deployment of the mask. The substrate 130 covers the opening 127 to hold the mask assembly 103 in position during installation of the cartridge 100 and may also prevent contamination.
  • the cartridge 100 is a pre-packed standalone assembly that is intended to be installed in the field without requiring any handling of individual mask components by aircraft technicians. Accordingly, the cartridge 100 is provided with quick connect oxygen line connections and quick connect mechanical connections such as quarter-turn bayonet (not shown), pin and slot connections ( Fig. 6-9 ), or "push and stab" connections ( Fig. 12 ) that provide for quick installation in the field without the requirement of tools or separate fasteners. However, it is to be understood that the cartridge 100 can also be installed with tools and separate fasteners.
  • the cartridge 100 includes a supplemental mask ejection device such as the spring-biased piston 131 shown in Fig. 2 .
  • the piston 131 is biased by a pair of coil springs 133 disposed in grooves 135 in the back of the piston 131.
  • the spring 133 is released from a retention mechanism and provides a force on the piston 131 in the downward direction with respect to the orientation of Fig. 2 . This force ejects the mask 109 from its cartridge to present it to the user.
  • the mask ejection device may be formed as part of the cartridge, as part of the housing or oxygen manifold (as shown and described herein in connection with Figs. 10-12 ) or as a part of some or all of the above components.
  • the cartridge in order to eliminate the ejection device from the cartridge, the cartridge may be provided with an end wall that is responsive to force from an ejection device mounted on the manifold.
  • the cartridge may be formed with one or more openings in the top and the one or more openings may be covered by a flexible covering such that the ejection device may act upon the mask 109 to deploy it.
  • a bank of cartridges are shown.
  • cartridge 100 On the left side with respect to the orientation of Fig. 3 , cartridge 100 is shown with the mask removed for clarity.
  • the cartridge 100 includes a quick connect fitting for attaching to a manifold 140.
  • alternate embodiments for the cartridge are shown.
  • a cartridge 150 In the middle position, a cartridge 150 is shown.
  • the cartridge 150 includes a piston 153 sealed with 0-rings 156.
  • the piston 153 is actuated by the pressure of the oxygen and ejects the mask from its cartridge.
  • another alternate gas pressure actuated piston is shown with cup seals 159 to form the pressure chamber above the piston.
  • a pair of cartridges 100 and 150 are shown in relation to the door 160 leading to the inside of the aircraft cabin.
  • the door 160 may be opened by a solenoid-operated actuator 163.
  • the door 160 could be held by a mechanically operated latch capable of being released by the force of the ejection of the mask 109.
  • the mask 109 is ejected from its cartridge by the force of the piston which may be spring-biased or pressure actuated as described above. If the flow of oxygen is initiated when the masks are presented, then the masks may be ejected by pneumatic pressure as described above.
  • mask 109 is ejected from cartridge 180 by a bellows chamber 183.
  • the bellows chamber 183 fills with oxygen causing it to expand and push the mask 109 downward with respect to the orientation of Fig. 5 .
  • Cartridge 200 includes side walls 203 and an end wall 206. Extending from end wall 206 are a pair of studs 209 that can be used for attaching the cartridge 200 to a support structure.
  • the studs have a body portion 212 and an enlarged head 215 for engaging with a slot having an enlarged opening leading to a slot. By inserting the head 215 into the enlarged opening and rotating the cartridge 200, the body portion 212 can be received and retained by the slot as will be evident to those of ordinary skill in the art.
  • an opening 207 surrounded by an adapter 218.
  • the adapter 218 is provided with an O-ring 221 capable of engaging with the oxygen manifold to provide for fluid communication between the oxygen manifold and the oxygen conduit 224 in the cartridge 200.
  • Other connecting means such as quick connects and the like could also be used and the cartridge 200 could therefore be supported from these other structures disposed around the central opening.
  • the adapter 218 leads to a bladder 227 the outlet of which is in fluid communication with the conduit 224.
  • the conduit 224 is coiled above the remaining components such as the reservoir bag, straps, and oronasal mask.
  • a cover 230 is attached to the cartridge 200 at the end opposite from the end wall 206. In operation, the flow of oxygen from the manifold into the bladder 227 causes the bladder 227 to expand and force the mask assembly to push the cover 230 off of the cartridge and causes the mask assembly to exit the cartridge 200.
  • a diaphragm 250 is formed from a flexible sheet of material.
  • the diaphragm 250 may be attached on opposite sides of the cartridge 253 at midwall between the top 256 and bottom 259 of the cartridge.
  • the cartridge 253 has a central opening 268 which is surrounded by a gasket 271 when the cartridge 253 is in position.
  • the central opening 268 is in fluid communication with gas passageway 274 in the manifold 265.
  • a mask assembly 277 (including straps, etc. as described above in connection with Fig. 2 ) is provided for delivering the breathing gas to the user.
  • a hose assembly 280 connects the mask assembly 277 to a fitting 283 on the diaphragm 250.
  • the mask assembly 277 and hose assembly 280 are folded and stowed in the cartridge 253 prior to use (as shown in Fig. 6A ).
  • the flow of breathing gas in the direction of arrow 284 from the manifold 265 causes the diaphragm 250 to move downward with respect to the orientation of Fig. 6B .
  • the force of the diaphragm 250 against the mask assembly 277 causes it to deploy.
  • the force of the diaphragm 250 against the mask assembly 277 provides for deployment of the mask assembly 277 regardless of the location of the cartridge 253 which may include overhead in the ceiling of the aircraft, in the sidewalls of the aircraft, or in the seat assembly.
  • Cartridge 300 has side walls 303 and an end wall 309.
  • the end wall 309 may be provided with studs 312 for engaging with support structure on oxygen manifold 308 ( Figs. 8-9 ) as described above in connection with studs 209.
  • a central opening 310 is surrounded by an adapter 315 having an 0-ring 318 disposed thereon.
  • the adapter 315 may be inserted into the oxygen manifold 308 such that a seal is formed by the 0-ring 318.
  • a spring 321 is seated in a retaining member 323.
  • the retaining member 323 may be provided with a major portion having an H-shape in cross-section.
  • the top section 324 holds the spring 321 and prevents it from making contact with the coiled breathing conduit 327.
  • a tube 330 extends between the adapter 315 and the breathing conduit 327 and is disposed through an opening in the center of the retaining member 323.
  • the bottom of the retaining member 323 is hollow and provides additional support for the coiled breathing conduit 327.
  • the top of the retaining member 323 is provided with a flange 333 that extends outwardly.
  • the spring 321 is compressed between the end wall 309 of the cartridge 300 and the dividing wall 336 in the retaining member 323.
  • the spring 321 is biased against the retaining member 323 in the downward direction with respect to the orientation of Fig. 7 .
  • a latch 350 connected to retaining member 323 holds the spring 321 in the compressed state as shown in Fig. 7 .
  • the latch 350 is engaged with a surface on the oxygen manifold 308.
  • a solenoid actuated piston 360 ( Figs. 8-9 ) may be provided to disengage the latch for deployment of the masks. The piston on the solenoid disengages the latch such that the spring is allowed to expand and push into the mask assembly which in turn pushes against the cover 365 to open the end of the cartridge 300. After the cover 365 is released, the mask assembly exits from the cartridge 300.
  • an alternate embodiment of the invention provides for mounting the springs external to the cartridge.
  • manifold 400 supports a pair of latches having a catch member 403, a shaft 406, a head 409 and a pair of springs 412.
  • the springs 412 are pre-loaded in compression between the head 409 and the bottom surface 415 of the manifold 400.
  • a cartridge 420 has a pair of openings 423 in the top wall for receiving the springs 412 and their supporting structure.
  • the cartridge 420 may be provided with studs 413 for mounting the cartridge 420 on the manifold 400.
  • the cartridge 420 also includes a central opening 426 surrounded by an adapter 429. The central opening is in fluid communication with a breathing conduit 432 connected to an oronasal mask assembly. Accordingly, oxygen from the manifold 400 can flow into the breathing conduit 432 when the cartridge 420 is attached to the manifold 400.
  • a spacer member 430 is disposed between the springs 412 and the mask assembly.
  • a solenoid actuated piston assembly 450 is mounted on the manifold 400 and is disposed such that the pistons disengage the catch members 403 from the oxygen manifold 400. Once the catch members 403 are free, the springs 412 push against the spacer member 430 which pushes the mask assembly against the cover 480 and out of the cartridge 420.
  • the present invention may be used with all types of aircraft supplemental oxygen delivery systems.
  • delivery systems There are two primary types of delivery systems: systems whose deployment is initiated by the turning on of a central oxygen supply and systems whose deployment is initiated by an electrical signal.
  • the pneumatic pressure can be used to push the mask out of its container as described above. Because the containers are normally stored in a housing that typically includes a cover, the pneumatic pressure of the oxygen can be used to unlatch the cover or the cover could be unlatched by the masks pressing against the inside of the cover as they are ejected from their containers.
  • a valve may be inserted in the oxygen supply to prevent a sustained flow of oxygen out through a mask which is not being used. In Fig. 6C , such an arrangement is shown where the valve 285 is inserted at the point where the hose assembly 280 attaches to a fitting 283 on diaphragm 250.
  • the valve 285 may be a simple on/off toggle valve or a clip closing off hose assembly 280.
  • This valve may be attached to a lanyard 288 and when mask assembly 277 is pulled to a user's face, the lanyard 288 will actuate the valve 285 or release the clip allowing oxygen to flow.
  • the valve could also be electronic such that it would be activated by the user's drawing in a breath after donning the mask and creating a slight negative pressure in the mask and tubing, which would be sensed by the electronic switch allowing the oxygen to flow.
  • Fig. 6D illustrates a switch that may be mounted on the manifold or the cartridge. Oxygen flows into a bellows or bladder ejecting the mask as described previously but cannot flow into the tubing of the mask until the electronic valve 289 senses the presence of a user and allows the oxygen to flow to the mask assembly 277.
  • Fig. 6E is a variation of the electronic switch located in the oxygen supply.
  • the electronic switch 296 allows oxygen to flow into the bellows or bladder through central opening 268, ejecting the mask assembly 277 as described previously.
  • the switch 296 is programmed to allow the flow of oxygen to occur for only the length of time needed to eject the mask, after which the oxygen supply is cut off by the electronic switch 296.
  • the electronic switch 296 does not reopen, allowing the flow to continue, until it senses by means of sensor tube 294 that the user is taking a breath.
  • the oxygen source is often a chemical oxygen generator or a sealed oxygen cylinder serving only the group of masks contained in one or more housings.
  • the oxygen supply may be initiated by the users reaching for the oxygen masks and pulling them toward their faces. Accordingly, the ejection of the masks is not associated with the flow of oxygen as the masks have to be ejected prior to actuation of the source of oxygen gas.
